Muslims took over British underworld the day Twin Towers fell

In traditional Islamic headgear, Asian ex-gang member Amir poses with his sword and issues the stark warning: "Britain's underworld belongs to the Muslims."

The 21-year-old, whose organisation turned over thousands of pounds a day from drug-dealing and credit card scams, claims a post-9/11 fear of terrorism has allowed Muslims to develop a stranglehold on our criminal community.

Through Islam, he says, they have numbers which cannot be matched, and rival gangs are being forced out by ruthless Islamic criminals who only deal with each other.

They recruit black and white members in Britain's jails, tempting them to convert to Islam in exchange for a cushier life inside.
